Hi, thank you for visiting this blog. I’m a professional software developer since Y2K. A blogger since Y2K+5. Thinking and learning about all kinds of stuff since forever. Developing software is one of my great passions in life. I'm currently working at iChoosr as a senior something dude during the day, hacking on Node.js, Ruby, F#, Clojure and Erlang stuff at night. I also enjoy running, reading books and listening to music.

JavaScript

Earlier this week, I read this great article titled “Writing Fast, Memory-Efficient JavaScript” by Addy Osmani. This is a highly recommended read for anyone involved in writing JavaScript code. The topics that I found to be particularly interesting were the apparent fact that it’s better to avoid the delete keyword and cached functions in the module pattern. The major down-side that I see when using cached functions is that you can’t have any private variables

Node.js

Last year I wrote this blog post where I described a couple of ways on how to tackle routing with Express. In the mean while I moved on from the “Plain Old School” approach to an approach where I replaced underscore.js with node-require-directory. Setting up node-require-directory is quite easy. In the routes folder, we just need to add an index.js module with the following two lines: var requireDirectory = require(‘require-directory’); module.exports = requireDirectory(module); Setting up

.Net 4.0Tools and UtilitiesVisual Studio

I noticed this blog post from Scott Hanselman the other day about Visual Studio Express 2012 for Windows Desktop. This post included a screenshot from the installation program. Something that really took me by the throat is this: Notice that the Express edition of Visual Studio seems to require no less than 4.15 GB of hard disk space! So I decided to try out the Professional edition of Visual Studio just to find out that

Books

At first I was a bit skeptical whether I should spend time listening to the audio version of this book. I’ve heard and read both great things as well as bad things about the book. A few people recommended it, while a couple of others discouraged me from reading it. But after getting through only a few chapters I was completely hooked. The book tells the life story of Steve Jobs from birth until his

The last couple of weeks I’ve been playing with a load testing tool called Blitz. You can create a free account which provides you the ability to ‘rush’ your web application with 250 concurrent users (or less) for 1 minute. And of course, you can increase both the number of concurrent users as well as the duration of the load tests after you specify a credit card number. The interface is pretty slick, as it

Books

A couple of weeks ago, I digested the audio version of Outliers – The Story of Success, written by Malcolm Gladwell. In this book, the author tells the story of a couple well-known and also lesser-known individuals that are considered to be successful. But what’s particularly interesting about this book, is the analysis the author makes to uncover the exact reason(s) that make these talented people stand out from the masses. There seem to be

Esoterica

In the previous blog posts I discussed the importance of getting enough sleep and physical exercise. For this post I want to provide a quick shout out of the social media diet that I’m currently trying out. My name is Jan and I don’t have a Facebook or a Netlog account of some kind. I do have a Google+ account that I haven’t visited in like four months. I also have a Twitter account that

Esoterica

In the previous blog post, I discussed the importance of getting enough sleep every single night. For this post I want to emphasize the importance of physical exercise. I’m writing these words after having run approximately 15 kilometers. This I do three times a week, every week, throughout the whole year with only a few exceptions. And the reason for this is pretty obvious. Since I started running back in 2007, I never felt better.
